Originally transmitted in 4 episodes on BBC1 between 28th December 1968 and 18th January 1969, The Krotons starred Patrick Troughton as the second Doctor. The soundtrack (or "special sounds") were created by Brian Hodgson and the BBC Radiophonic Workshop, who said:

For this story I mainly used the “Crystal Palace”, so called because its case was made of clear Perspex which exposed its workings. This machine, created by our engineer Dave Young, could mechanically sample 16 inputs and combine them into a single output in 4 prearranged patterns. The progression of the patterns was deliberately slow to create textures of sound. I was very much interested in exploring changing aural textures in tracks such as “The Learning Hall” and “Kroton Theme”.

Generating and manipulating music and sound effects defines sound design, a process that is common on TV and film productions nowadays. However The BBC Radiophonic Workshop was way ahead of the game in the 1960s. Brian Hodgson was a member of the Workshop working closely with the seminal figure of Delia Derbyshire. As the original sound effects creator for Doctor Who he was responsible for the chilling Dalek voices and the powerhouse sound of the Tardis lifting off (created by running a back door key for his mother's house along the bass string of a gutted piano and treating it electronically). His highly innovative techniques are fully on display on this collection of 'special sounds' that provided the background to Doctor Who - The Krotons.
